Abstract
An electromagnetically operated relay in which an elongated armature is pivotally supported adjacent three pole members. One pole member has a surface adjacent one end of the armature. The second pole member has a surface adjacent the armature on the opposite side of the pivot from the first pole member. The third pole member has an elongated surface extending on either side of the second pole member between the outer end of the armature and the pivot. A permanent magnet is connected in a low reluctance magnetic path between the second and third pole members to produce a permanent field biasing the armature toward the second and third pole members. An electromagnet connected in the low reluctance magnetic path between the first and second pole members, when energized from a direct current source, increases the level of flux in the first and third pole members and decreases the level of flux in the second pole member, causing the armature to pivot toward the first pole member.
